Spot on, erich. I've never felt under gunned with my post war 16 gauge guns. I don't drag a drilling through the wet and mud of a duck blind, and that's the only place they might be at a real world disadvantage.
I'll always be envious of that sweet handling little 6.5X58R drilling of yours. There is also the satisfaction you must feel in tailoring special ammo for it. I also envy anyone with the patience and talent to carve out a set of claw rings. It sure trimmed down the 7X57R drilling and made it a far better out-west hunting gun...more mobile.
